The overarching theme of the research pursued by my group is solid-state mechanical and chemical kinetics in both crystalline and amorphous planetary materials. Important in this introduction is to note that the work is highly interdisciplinary, with multiple interactions in geophysics and petrology within the department and in materials science and solid mechanics beyond the department. |  | Karen M. Fischer

The overall goal of my research is to more clearly image the structure of the Earth's crust and mantle using seismic waves in order to better understand dynamic processes inside the Earth. Our recent work has focused on two topics: the continental lithosphere and its interactions with the deeper mantle, and mantle flow and melting processes in subduction zones. These studies blend analysis of observed seismic body and surface waves - often gathered through temporary field deployments of seismic stations - with numerical modeling of mantle processes and prediction of theoretical waveforms. |  | Don Forsyth

I am a seismologist and marine geophysist. My research has developed along four major lines: ocean-bottom seismometer and marine geophysical studies of oceanic crust and upper mantle, isostasy of continents and oceans, lateral heterogeneities and azimuthal variations in seismic velocity in the mantle related to convection, and the dynamics of mid-ocean-ridge tectonics. |  | David L. Goldsby
Geological Sciences, Department of
I am interested in the deformation of geological materials, studies of rock friction and plastic flow of ice. My rock friction research focuses on gaining an understanding of the fundamental micromechanical processes that are responsible for the dependence of frictional resistance on slip speed, slip displacement and time, with important applications for understanding earthquake mechanics. My ice deformation research focuses on understanding grain-size sensitive flow processes and the ways these may control the deformation of ice on the Earth in glaciers and ice caps as well as on icy satellites, such as those of Jupiter and Saturn. |  | L. Peter Gromet

My major research interest is on understanding the processes that control the tectonic evolution of ancient collisional mountain belts. These regions provide windows into the middle and lower crust and record information about their behavior during continental collision. This type of work requires an integration of field, petrographic, and laboratory expertise, the latter including clean laboratory operations and mass spectrometric analyses. |  | Meredith Hastings

My research focuses on the reactive nitrogen cycle, with an emphasis on nitrate deposition. My interest in reactive nitrogen (e.g., NOx) extends from its connection to air quality through its impact on ozone and hydroxyl concentrations to the biogeochemical cycling of nitrogen in the earth system via formation of nitric acid (or nitrate), a major component of acid rain and a source of biologically available nitrogen. |  | James Head
Geological Sciences, Department of
Professor Head studies themes of planetary evolution and the role of volcanism and tectonism in the formation and evolution of planetary crusts. Several research projects are underway in the field in Antarctica, on the Earth's seafloor, and in assessing data from planetary surfaces to study climate change on Mars, volcanism on the Moon, Mars and Venus, the geology of the surface of Mercury and the tectonic and volcanic evolution of icy satellites. |  | Timothy Herbert

Understanding how the earth's climatic system, particularly the ocean, adjusts itself to perturbation on various timescales drives most aspects of my research. My recent projects include application of alkenone paleotemperature determinations to problems of Plio-Pleistocene climate change, development of new tools to scan sediment cores non-destructively, and application of orbital stratigraphy to solve problems in earth history over Cenozoic and Mesozoic time. |  | John Hermance

My research is in the area of environmental geophysics and hydrology. I advocate preserving the subsurface environment through non-invasive investigations using methods such as ground penetrating radar, magnetic surveys, and DC resistivity. This offers cost-effective means for obtaining a quantitative, spatially representative overview of subsurface conditions and avoids puncturing drums of common toxins which could enormously complicate site remediation and threaten the natural environment. |  | Paul Hess

My interests are in experimental rock mechanics, deformation mechanisms in both crustal and mantle lithologies, structural geology, application of experimental flow laws to geophysical and geological observations. I also investigate the processes that control the mechanical behavior of rocks using optical and electron microscopy in conjunction with theoretical considerations. I study the physical and chemical properties of rocks and minerals from a material science perspective. |  | Yongsong Huang
Geological Sciences, Department of
I specialize in the development and application of organic isotope geochemistry to problems in the environment, paleoclimate, paleohydrology, and astrobiology. My goal is to create new approaches and applying these approaches to understanding mechanisms and solving prominent problems in continental climatic change, environmental response to climate change and in astrobiology. |  | Yan Liang

The central themes that run through my research are the processes that modify solid surfaces and the spatial and temporal scales that control environmental processes on the Earth. Because surfaces lie at the interface between the solid interior of a planet (from the shallow subsurface to the deep interior) and the fluid exterior (atmosphere, hydrosphere, etc.), their composition and morphology record the interesting interplay between interior and exterior processes. |  | Stephen Parman

My research focuses on the chemical evolution of the Earth, moons and planets. I use a combination of high-pressure, high-temperature experiments to understand the chemical behavior of geomaterials at depth, and use this information to interpret the geochemical rock record. |  | Marc Parmentier
Geological Sciences, Department of
My research centers on understanding the roles of melting, melt migration, and mantle dynamics on the long-term evolution of the interior of the Earth and other planetary bodies. This includes convective motions that give rise to largest scales of mantle overturn, that we associate with plate tectonics on the Earth, as well as smaller scales of motion associated with intraplate and plate boundary volcanism. An understanding of the physics and scaling laws governing these processes allows predictions of planetary behavior which can be compared with available observations. |  | Carle Pieters

I research global-scale paleoceanography and local-scale estuarine oceanography. I am interested in the paleoceanographic evolution of the Cenozoic climate-ocean system and the interaction between global tectonic and orbital forcing on the evolution of climate. I study changes on the modern annual cycle and on geologic time scales. My estuarine oceanography research is on distribution and causes of low dissolved oxygen in Narragansett Bay. |  | James Russell

I seek to understand the patterns and causes of natural climate variability using paleoclimate records. I am particularly interested in the climate history of the tropics, including intertropical Africa and the El Niño Southern Oscillation system. My work involves the generation of high-resolution paleoclimate reconstructions using lake sediments, and synthesizing those records into regionally-coherent datasets to to test against climate models. |  | Malcolm Rutherford

The focus of my research is the experimental, field, and theoretical investigations of the phase equilibria of calc-alkaline magmas. The purpose is to establish mineral stabilities and compositions in these magmas as a function of the fugacities of the volatile species, temperature, and the total pressure. This type of phase equilibrium is used to assess the conditions in pre-eruption subvolcanic magma systems at Mount St. Helens, and in the pre-eruption magma system at Mount Pinatubo, Philippines. |  | Alberto Saal

Impact cratering is one of the few processes affecting all planetary bodies. Records can provide clues for contrasting geologic evolutions. The planetary record, lab experiments, field studies, and theoretical approaches allow exploring a process at scales we hope we never witness. My main research has been on the effect of impact angle on cratering and the role of the atmosphere in modifying the process. Different planetary environments, laboratory simulations, and theoretical models allow testing under extreme conditions and to extreme scales. |  | Jan Tullis

My research involves experimental investigations of the deformation mechanisms, microstructures, and rheology of crustal rocks. My goal is to infer details of the thermomechanical history from the microstructures and crystallographic preferred orientations preserved in naturally deformed rocks, and to provide fundamental mechanical data for modeling crustal and upper mantle deformation under various conditions. |  | Terry Tullis

I focus on understanding the mechanics of earthquakes. This involves a combination of lab experiments on the frictional behavior of rock and computer modeling of earthquakes that employs the constitutive relations that arise from the lab experiments. Computer modeling is used to determine if there are any signals that might be used for short - or intermediate - term earthquake prediction. We are trying to understand the processes responsible for the observed frictional behavior. |  | Thompson Webb
